If you leave the goat head in place, it flexes and breaks that seal constantly which means that the sealant is just along for the ride. Remove whatever is puncturing a tubeless tire (or sealant filled tube) and let the sealant do its job.
I was being flip and, hence, unclear. I agree. In any case, once you get back home, you should remove the goat head from the tire and tube (tire inspection most easily done by first removing stuff from the outside of the tire, then inverting the tire inside-out and carefully feeling for any sharp protrusions). The patch the tube and reinstall.
Also I understand it, if you get stabbed, you're supposed to leave the knife in and let the doc take it out. Same reason as the goat head: the knife acts as a plug.
